Probably a long shot, but what was the resolution? I have a 2008 GTI that has the same problem. The rear right window works in reverse on both the driver switch and the door switch. This definitely seems like a software issue vs hardware.I've got the same problem with the driverside rear window.
Push the switch down = window goes up, lift the switch up = window goes down! The one touch function of the switch is also not working. Annoying because when I put the windows down from the remote key fob that one window stays closed, when I close the others from the key fob that one windows goes down!
It started after it went into the dealer to get some minor damage fixed after some stupid woman drove into me.
The dealer is having problems trying to work out the cause and a fix for it, they've had it a week and I'm driving around in their loan car.... a VW Fox:thumbdown:
